اَللّٰهُمَّ اِنَّكَ قُلْتَ وَ قَوْلُكَ الْحَقُّ فِی كِتَابِكَ الْمُنْزَلِ عَلٰی صَدْرِ نَبِیِّكَ الْمُرْسَلِ: ’لَمَسْجِدٌ اُسِّسَ عَلَی التَّقْوٰی مِنْ اَوَّلِ یَوْمٍ اَحَقُّ اَنْ تَقُوْمَ فِیْهِ، فِیْهِ رِجَالٌ یُحِبُّوْنَ اَنْ یَتَطَهَّرُوْا وَ اللّٰهُ یُحِبُّ الْمُطَّهِّرِیْنَ‘ اَللّٰهُمَّ طَهِّرْ قُلُوْبَنَا مِنَ النِّفَاقِ وَ اَعْمَالَنَا مِنَ الرِّیَا وَ فُرُوْجَنَا مِنَ الزِّنَا وَ اَلْسِنَتَنَا مِنَ الْكِذْبِ وَ الْغِیْبَۃِ وَ اَعْیُنَنَا مِنَ الْخِیَانَۃِ فَاِنَّكَ تَعْلَمُ خَائِنَۃَ الْاَعْیُنِ وَ مَا تُخْفِی الصُّدُوْرُ رَبَّنَا ظَلَمْنَا اَنْفُسَنَا وَ اِنْ لَمْ تَغْفِرْ لَنَا وَ تَرْحَمْنَا لَنَكُوْنَنَّ مِنَ الْخَاسِرِیْنَ۔
Upon entering the Mosque one should perform two rakats prayer of respect. Then recite the Tasbeeh of H. Fatemah Zahra )s.a.(. And recite the Ziyarat-e-Jaameah and supplicate after that. It is better to supplicate as follows:
There was a place of H. Ali (a) behind this mosque and a salty water well in the front. There is no sign of this well today.
It is said that the finger-ring of the Prophet (s.a.w.a.) had fallen in it. Hence it is called 'Chahe Angushtari' (well of finger-ring) while it is also called 'Chahe Abe Dahaan' (Well of saliva).
It is said that the Holy Prophet (s.a.w.a.) had put his saliva in this well because of which its water became sweet.
A group of hyprocrites constructed a mosque in 9th Hijri so that they could oppose Islam and Muslims. The Prophet (s.a.w.a.) was asked to pray in it for its inauguration and as an offering.
The Holy Prophet (s.a.w.a.) said that he would do so on a suitable occasion. But the revelation of the verse... wal ladinat Takhad'u Masjidan Z'iraran wa kufran...' destroyed their plans and the Prophet (s.a.w.a.) ordered to demolish it.
